TIME INDICATOR.

Application filed June 3,

T 0 all whom it may concern:

Be it known that I, CARL 1V. Janene, a citizenof the United States, and a resident of WVestby, in the county of Vernon and State of lVisconsin, have invented a. new and useful Improvement in Time Indicators of Which the following is a full, clear, and on act description.

My invention relates to improvements in direct reading indicating or computing devices, and it consists in the combinations, constructions and arrangements herein dcscribed and claimed.

An object of my invention is to provide a device for use in banks and like institutions in the calculation of the number of days occurring between two given dates.

A further object of my invention is to provide a device that is adapted for use with the result sheet such as is disclosed in my companion application for patent for time indicator, filed June 3, 1921. Serial No. 474,692, in which I show a different form of device for carrying my invention into effect.

A further object of my invention is to provide a device that is simple in construction, compact, and readily operable.

A further object of my invention is to provide a device of the character described having means for disclosing results ordinarily requiring a great many computations without any manipulation of the device being required beyond an initial adjustment.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application in which Fig. 1 is a side elevation of the device, portions thereof being broken away and other portions being shown in section. and

Fig. 2 is a section through the device along the line Q-2 of Fig. 1.

In carrying out my invention. 1 provide apylinder 1 having ends 22. This cylinder is made of any suitable material. pref erably a light metal or wood. and is rigidly mounted on a shaft?) that is ournalled adjacent to its ends'ln spaced apart parallel upright supporting members st-. The ends of the shaft 3 extend beyond opposite sides of the supporting members 4& and have secured thereto knobs or handles 5 5, where 1921. Serial NO. 474,593.

by the cylinder 2 can be rotated the axis of the shaft 3.

The cylinder 2 is provided with a glass panel 6 in its peripheral wall. The panel 6 is cylindrical in form and occupies nearly the entire area of the periphery of the cylinder 2 leaving only two annular axially alined strips 7 and 8 at its ends. fThese strips are respectively divided by alined lines 9 and 1.0 into thirty-one index spaces 11. In each index space 11 is marked a nu Ineral and in the present embodiment of the invention. the numerals 1 to8l inclusive are employed. 2 These numerals are arranged in the order in which they occur in corresponding positions on the two strips 7 and 8.

' Mounted upon inclined arms 12-12 that are secured to the supporting members 4.--1

at will about in parallel relation is an indicator strip 13 that extends across the periphery of the cylinder 2 and is positioned adjacent to the latter, as best seen in Fig. 1. The indicator strip 18 has a width substantially the same as the distance between adjacent lines defining the spaces 11 on the strips 7 and 8. The indicator strip 13 also has spaced apart parallel lines 14 extending across its upper face to provide twelve spaces 15 in which are marked thenames ofthe months of the year. It is to be observed that the spaces 15 are arranged on that portion of the indicator strip that is positioned above the glass panel 6 and that the remote lines 1t are respectively substantially alined with the approximate edgesof the strips 7 and 8.

A guide plate 16 is fashioned into a cylinder arranged within the outer cylinder 1 and is secured thereto by means of pins 17, or like fastening means,that engage the end walls of the outer cylinder 1 and the inner guide cylinder 16. It is to be observed that the inner guide cylinder 16 is concentric with the outer cylinder 1 and is spaced therefrom so that a sheet 18 can be threaded through a slot 19 in the peripheral Wall of the guide cylinder 16 and passed entirely around the latter between the guide cylinder 16 and the glass panel 6 so that a portion of the length of the sheet may be obser ed through the glass panel. The Walls of the slot 19 are bent inwardly and then laterally. as best seen in Fig. 2 so that rounded surfaces will contact the sheet 18.

A drum or reel 20 on which the sheet 18 is wound. is mounted on a shaftv 21 that is journ'alled adjacent to its endsin end spaces 11.

walls of the cylinder 1. Knobs 22 are secured to the protruding ends of the shaft 21 to provide a means for occasioning the unwinding of the sheet 18 from the drum or reel 20 or the winding of the same thereon.

The sheet 18 is threaded through the opening 19 and around the guide cylinder 16in the manner described and is then secured at its end to a second drum or reel 23 that is mounted on a shaft 24. The shaft 24 is parallel with the shaft 21 and is likewise journalled adjacent to its ends in the end walls of the cylinder 1. Knobs 25 are secured to the protruding end portions of the shaft 24 to provide a means for manipulating the latter. The drums and 23 are normally held against rotation by friction members 26 and 27 which are passed through registering openings in the walls of 20 the cylinders 16 and 1 to project exteriorly of the latter. The friction member 26 is secured at its inner end by means of a screw 28 or the like to the adjacent. end wall of the guide cylinder, being passed around the drum 20. The friction member 27 is passed around the drum 23 and is secured at its inner end to the same end'wall of the guide cylinder by a screw 29 or the like. The

outer ends of the friction members 26 and 30 27 are connected by a cap 30 and a spring 31 is disposed between the latter and the outer cylinder 1 to urge the cap 30 outwardly and thus hold the drums 20 and 23 against free rotation.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The sheet 18 is formed to provide twelve sections. Each section is adapted for use in a particular month and the sections are ar ranged in the order of the months of the year, being formed integrally so as to form a single sheet. Each section has marked 5 thereon a plurality of spaced apart lines 32 which are intersected at right angles by spaced apart parallel lines 33, thereby providing a plurality of spaces 34 in which are marked in series numerals representing tabulated results. It will be observed that the i spaces 34 are arranged in twelve rows alined respectively with the spaces 15 and in thirty-one rows alined respectively with the Each of the spaces 34 with one exception on each section has two numbers marked thereon, each of which constitutes a part of two series of results, the results representing the numbenof days from a.

given date to a date indicated by the position of the space 34 with respect to the spaces 15 and 11. The remaining space 34 has but one number marked thereon, this number being 365 and constituting a part .of both series. The numbers of the two seriesa'are preferably formed in contrasting at 001cm cylinder 1 until the space To illustrate the operation of the device, let us assume that the date is June 26th. The section for the month of June will then be positioned on the guide cylinder 16 so that a portion thereof is visible through the glass window pane 6. This section will be arranged so that the space bearing the num her 365 will be positioned next to the indica-- tor strip 13, as illustrated. If it is desired to ascertain the number of days from the present date, June 26th to Jan. 26th of the following year, it is only necessary to glance at the space 34 positioned. beneath Jan! and opposite 26 and it will be observed that the result desired is 214. If the num ber of days from Jan. 26th of the presentyear to the present date-June 26th isto be ascertained, it is only necessary to glance at the same space 34 and it will be noted that the result desired is 151. In a like ner, the number of days from any date in the preceding or present year to the present date, or from the present date to a later date at all in order to ascertain the result desired.-

If the given date is not visible, it is only necessary to grasp the knob 5 and rotate the 34 positioned at the given date is visible. The knob 23-is manipulated each day to advance the section a distance equal to that between adjacent lines 9 and no further adjustment or Inanipulation-is required to ascertain the de-- sired results in the manner described during the entire day. It will thus be seen that a great economy in time and labor results when my improved device is used and that the possibility of error is reduced to a minimum, since no mathematical calculations are required. 1
